According to a tweet by Facebook product designer and UI guru Mike Matas, his team is now working with influential app designer Loren Brichter. That's right, the man behind Tweetie and Letterpress is now working for Facebook.

After being seemingly forgotten, a brand spanking new Tweetie 2.0 will launch tomorrow on the Mac App Store. Tweetie 1.0 has long been our favorite twitter app for Mac, so we can't wait to see what version 2.0 will bring. Finally!

When Twitter swallowed Tweetie maker Atebits, they declared that an official Twitter client—a la Android's—was on its way. You'll be happy to hear that Twitter has barely changed the iPhone's best Twitter app, except where it counts: Price.

Last month, Twitter bought Tweetie—our most favorite of all iPhone Twitter apps—with the intention of rebranding it as the free, official Twitter for iPhone app. It looks like that change is imminent—Tweetie 2 disappeared from the App Store this morning without a trace, and presumably Twitter for iPhone will show up…

The guy behind recent Twitter purchase Tweetie, along with the dude behind Borange, have put together a characteristically pretty SMS replacement app called Textie. There are two things you should know about it: It's free, and it works.

Among the changes of Tweetie 1.3 are a dark theme, various UI tweaks, Tweetshrink integration, full-size profile image viewing (yay), and a bunch of bugfixes. Grab it now if you like using the best Twitter app available for the iPhone.
